Moreover, a hook switch 77 is opened to inactivate a speaker amplifier 71 and a hook switch 85 is closed, then the music signal from the sound source section 61 is sent to the telephone line while being superimposed on the transmission signal from a transmitter 11. Thus, the music is sent to the telephone line as the BGM automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to improvements in the ringing of a telephone device when a call is received and the transmission of background music (BGM) during a call.

(Prior art) When a conventional telephone device receives a call, it generates a ringing tone by generating an oscillation signal using a bell generating circuit, driving a speaker force or a piezoelectric element, or by ringing a gong bell. I'm letting you do it. In this case, the volume of the ringing tone is generally changed over several levels using a switch.

Additionally, telephone devices have been known that allow BGM to be played over the line during a call. Conventionally used BGM
The transmission method is to input BGM from an external sound source such as a tape recorder through a connecting cable, or to use a hold music IC.
There is a method in which the 80M card is also used, a method in which a card memory for the 80M card is installed, etc.

(Problems to be Solved by the Invention) In contrast to the monotonous ringing tone of conventional telephone devices, there is a desire from users to select a ringtone that is more pleasant to the ear and suits their tastes. In addition, the volume of the ringtone in conventional systems is fixed at the volume selected by a switch, so there is a problem that the ringtone volume may be too low or too loud depending on the time of day.

Regarding BGM during a call, all conventional devices require a special operation to play BGM during a call, and none of them are designed to automatically play BGM at the same time as the call starts.

Furthermore, the volume and number of BGM songs are often fixed.

Therefore, an object of the present invention is to enable the user to select a favorite music as a ring tone, to automatically play that music as BGM on the line when a call starts, and to have the ring tone and BG
To provide a telephone device that can automatically change the volume, sound quality, and track title of music as M depending on the time zone.

[Structure of the invention]

(Means for Solving the Problems) A first aspect of the present invention is a telephone configured to detect an incoming call from a telephone line and generate a ring tone, and detect an off-hook state and seize the telephone line. The apparatus includes: a sound source means for outputting a predetermined musical tone signal; a means for generating a ring tone based on the musical tone signal when an incoming call is detected; and a means for transmitting the musical tone signal to a telephone line when an off-hook condition is detected. Provided is a telephone device comprising:

Further, in the second invention, in addition to the above configuration, the sound source means has means for generating musical tone signals for a plurality of songs, and further includes means for setting a time period, and a means for setting a time period. means for correspondingly setting the track title, volume and sound quality;
means for determining whether or not the time when the incoming call is detected belongs to the time zone; and a means for instructing the sound source means to select a song corresponding to the time zone to which the incoming call belongs, and outputting a musical tone signal for that song. To provide a telephone device comprising: a means for adjusting the musical tone signal to a volume and tone quality corresponding to a time zone to which an incoming call belongs.

(Function) According to the first invention, when there is an incoming call, predetermined music is output as a ring tone. Subsequently, when the handset is taken off-hook and a call is initiated, the above music is automatically switched to BG.
M on the telephone line.

Furthermore, according to the second invention, selection of the ring tone and BGM track, volume, and sound quality are automatically performed according to the time zone. The structure of the main part of a preferred embodiment is shown. In the same figure, line connection terminals Ll, L
2 is connected to an external telephone line (not shown). The line connection terminals Ll, L2 are connected through the rectifier bridge 1 to the internal communication line 3.5 of this telephone device. A transmitter 11 and a receiver 13 of a handset 9 are connected to the internal communication line 3 via a speech network 7 . A line switch 15 for line capture is inserted into the positive internal communication line 3. This line switch 15 is driven by a hook switch 17 that is linked to on-hook/off-hook of the handset 9. That is, when the handset 9 goes off-hook, the hook switch 17 closes and the line switch 15 closes.
is turned on, thereby seizing the telephone line. That is, the telephone line is connected to the speech network 7 and a conversation is started.

In this state, the voice signal output from the handset 11 is sent through the speech network 7 to the internal communication lines 3, 5 and then to the telephone line, and the signal from the telephone line is sent to the internal communication line 3.5. and is provided to the handset 13 via the speech network 7.

An incoming call detection circuit 25 is also connected to the line connection terminals Ll and L2 via a DC cut capacitor 21 and a rectifier bridge 23 in this order. A 16 Hz incoming call signal, which is intermittently input from the telephone line with a duration of 1 second and an interval of 2 seconds, is applied to the incoming call detection circuit 24. The incoming call detection circuit 24 is driven by the incoming call signal and outputs a bell signal of a predetermined frequency during its duration. This bell signal drives the photocoupler 27, causing the photocoupler 27 to output a square waveform voltage signal synchronized with the bell signal. This square wave signal is given to one control section and an incoming call time determination section 29.

When the incoming call time determining section 29 first receives the square wave signal, it refers to the clock 31 to recognize the incoming time, and provides the time information to the comparing section 33 . Note that an initial setting switch 35 for time setting is connected to the clock 31.

When the comparison unit 33 receives the incoming call time information, the comparison unit 33 selects the time zone setting unit 3.
The time zone information is read from 7. This time period setting section 37 is provided with identification information of each time period into which the day is arbitrarily divided and time information indicating the start and end of the time period by operating the pushbutton groups 39 to 49 in advance. set in memory. Note that the settings can be monitored on a display 51. The preset time zone information is read out from the memory and sent to the comparison section 33 in response to a command from the comparison section 33 when an incoming call is received, as described above. The comparison section 33 is
By comparing each time zone and the time of incoming call, it is recognized to which time zone the time of incoming call belongs, and the identification information of the time zone to which it belongs is sent to the control section 19.

The identification information for each time zone set in the time zone setting section 37 is as follows:
It is also given to the volume/source/tone quality setting section 55. Volume·
In the source/tone quality setting section 55, information indicating the volume, track name, and tone quality for each time period is set in advance by operating the setting key 55 in its memory.

The control unit 19 is constituted by a microcomputer, and when it receives time period identification information from the comparison unit 33, it receives information on the volume, track name, and sound quality (these are (which is a digital code) is provided to the read data latch unit 57. The data latch unit 57 latches information from the control unit 19, of which the track information is sent to the sound source unit 61 via the track decoder 59, and the volume information and sound quality information are sent to the volume D/A converter 63 and the sound quality D/A, respectively. Volume adjuster 6 via converter 65
7 and tone adjuster 69. At the same time, the control unit 19 controls the sound source unit 61 in synchronization with the square wave signal indicating the incoming call from the photocoupler 27, that is, in synchronization with the input period of the incoming call signal.
is driven intermittently.

The sound source section 61 is connected to a music memory 62 having musical sound data (digital codes) of a predetermined number N (for example, 8 songs) of music, and when driven, stores the musical sound data of one music designated by the music decoder 59. 62, converts it into an analog tone signal, and outputs it. The music memory 62 can be a ROM in which predetermined songs are written in advance, a replaceable card ROM, or an RA in which you can freely write your favorite songs from an external sound source or microphone.
M (or rewritable ROM) etc. can be adopted. The overall volume of the output musical tone signal from the sound source section 61 is adjusted by a volume adjuster 67. In this case, the volume D/A converter 63
If the number of bits of the volume information inputted into the system is about 3 or 4 bits, it becomes possible to adjust the volume in 8 or 16 levels, that is, to adjust the volume almost without permission. The tone adjuster 69 adjusts the balance of high and low tones of the musical tone signal whose volume has been adjusted. In this case, if the number of bits of the sound quality information input to the sound quality D/A converter 65 is, for example, 2 bits, then
It is possible to adjust the sound quality in several levels such as treble emphasis, middle range, and bass emphasis, and this level is probably sufficient for practical use.

The musical tone signal after music selection, volume adjustment, and tone quality adjustment is given to the speaker amplifier 71. The activation/deactivation of the speaker amplifier 71 is controlled by a relay switch 75. The relay switch 75 has the track number, volume, and sound quality information output from the data latch section 57, and the hook switch 7
7 is closed (that is, the handset 9 is in an off-hook state), it is closed by a signal from the AND gate 79, and the speaker amplifier 71 is activated. Therefore, only when the handset 9 is on-hook,
A musical tone signal is output from the speaker amplifier 71. In this case, since the sound source section 61 is driven intermittently in synchronization with the incoming signal, the musical tone signal is also intermittently output in synchronization with the incoming signal. This musical tone signal is applied to the speaker 73 and output as a ring tone only when the ring tone selector switch 81 is set to the amplifier 71 side. When the selector switch 81 is set to the opposite side, the speaker 73
A bell signal from the incoming call detection circuit 25 is inputted to the incoming call detection circuit 25 via the transformer 83. Therefore, at this time, there is no music, but a bell sound similar to the conventional one is output as a ring tone.

The control unit 19 is also connected to a hook switch 84 that is linked to on-hook/off-hook of the handset 9, and when it receives a signal from the hook switch 84 indicating that the handset 9 is off-hook following input of a square wave signal from the photocoupler 27, The sound source section 61 is continuously driven until the next signal indicating on-hook is received. Therefore,
After going off-hook, the sound source section 61 continuously outputs musical tone signals. Also, due to this off-hook, the line switch 15
is turned on and seizes the telephone line, so that a conversation between the handset 9 and the telephone line is initiated. Furthermore, this off-hook opens the hook switch 77 to deactivate the speaker amplifier 71, and the hook switch 85 closes. Therefore, the musical tone signal outputted from the sound source section 61 and subjected to volume adjustment and tone quality adjustment is not given to the speaker 73, but instead passes through a low-pass filter 87 for removing unnecessary bands, and is transmitted as a transmission signal from the transmitter 11. and then sent out to the telephone line. In this way, the selected music and the volume and sound quality are adjusted to flow over the line as BGM.

As is clear from the above explanation, when an incoming call is received, the selected music is output as a ringtone from the speaker 73 after adjusting the volume and sound quality, and when the handset 9 is subsequently taken off-hook, the music is BG during call automatically
M and is transmitted to the telephone line. The degree of song selection, volume adjustment, and sound quality adjustment can be set for each time period, so you can select your favorite song as the ringtone and BGM, or increase the volume of the ringtone during relatively noisy hours. In addition, it is possible to make selections with a high degree of freedom, such as making the sound quality clear and making the ringing sound softer and quieter during quiet times such as late at night.

In the embodiment shown in FIG. 1, drive control of the sound source section 61 is performed according to software using a microcomputer (one control section), but FIG. 2 shows a configuration example in which this is performed only by hardware. . In the same figure, the sound source section 61 becomes active when it receives an "H" level voltage signal from the OR gate 89, and becomes inactive when it receives an "L" level signal. The output signal of the photocoupler 27 is applied to the OR gate 89 via an inverter 91 . When a call is received, the photocoupler 27 outputs an H level signal during the "L" level interval period during the manual input period of the incoming signal.
The sound source section 61 receiving the inverted signal is in an active state during the input period of the incoming call signal, and is in an inactive state during the interval period, and outputs a musical tone signal intermittently.

The OR gate 89 is also supplied with the Q output of the start flip-flop 93. This start flip-flop 93 receives the output of a start shot multivibrator 95 at its set terminal S, and this multivibrator 95 is connected to the handset 9.
emits a single pulse when the hook switch 97 is turned on or when the manual start button 99 is pressed when off-hook.

Therefore, when the handset 9 is off-hook, a pulse is emitted from the one-shot multivibrator 95, the flip-flop 93 is set, and its Q output becomes "H" level, so that the sound source section 61 is continuously activated from then on. Become.

The Q output of the stop flip-flop 101 and the reset pulse from the reset switch 103 are applied to the reset manual power R of the start flip-flop 93. The stop flip-flop 101 is configured to receive the output of the stop one-shot multi-vibrator 105 in its setting force S, and the stop one-shot multi-vibrator 105 is turned on when the hook switch 107 is turned on by the on-hook of the end set 9. outputs a single pulse when the stop button 109 is pressed or when the manual stop button 109 is pressed.

Therefore, when the handset 9 which was once off-hook is brought on-hook, the one-shot multi-bye break 105
A set pulse is issued to the stop flip-flop 101 and its Q output rises to the "H" level, which resets the start flip-flop 93 and returns its Q output to the "L" level. is returned to its inactive state.

The output of the reset switch 103 and the output of the inverter 91 are applied to the reset power R of the stop flip-flop 101 through the OR gate 111. Therefore, when the reset switch 103 is pressed or when an incoming call signal is input, the stop flip-flop 101 is reset.

As can be seen from the above explanation, even with the configuration shown in FIG. 2, the sound source section 61 is continuously driven in synchronization with the incoming signal when a call is received, and continuously driven during a call. The same effect as the embodiment shown in FIG. 1 can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, predetermined music is output as a ring tone, and the music is automatically transmitted as BGM to the telephone line when the user goes off-hook. Furthermore, since the music selection, volume and sound quality can be adjusted for each time period, the degree of freedom in music selection is increased and the volume and sound quality can be adjusted appropriately depending on the time period.
